One question remained yet to be decided¹; it was necessary to choose a favorable spot for the experiment. According to the advice of the Observatory² of Cambridge, the gun must be fired perpendicularly³ to the plane of the horizon, that is to say, toward the zenith. Now the moon does not traverse the zenith, except in places situated⁴ between 0° and 28° of latitude⁵. It became, then, necessary to determine exactly that spot on the globe where the immense Columbiad should be cast.

On the 20th of October, at a general meeting of the Gun Club, Barbicane produced a magnificent map of the United States. “Gentlemen,” said he, in opening the discussion, “I presume that we are all agreed that this experiment cannot and ought not to be tried anywhere but within the limits of the soil of the Union. Now, by good fortune, certain frontiers of the United States extend downward as far as the 28th parallel of the north latitude. If you will cast your eye over this map, you will see that we have at our disposal the whole of the southern portion of Texas and Florida.”

It was finally agreed, then, that the Columbiad must be cast on the soil of either Texas or Florida. The result, however, of this decision was to create a rivalry⁶ entirely⁷ without precedent⁸ between the different towns of these two States.

The 28th parallel, on reaching the American coast, traverses the peninsula of Florida, dividing it into two nearly equal portions. Then, plunging⁹ into the Gulf¹⁰ of Mexico, it subtends the arc formed by the coast of Alabama, Mississippi, and Louisiana; then skirting Texas, off which it cuts an angle, it continues its course over Mexico, crosses the Sonora, Old California, and loses itself in the Pacific Ocean. It was, therefore, only those portions of Texas and Florida which were situated below this parallel which came within the prescribed conditions of latitude.
